Rube - am glad to hear you fixed the issue.
This ICP is my first interaction with the local IH dealer. Called and spoke with the friendly parts person. He asked for the last 8 of my vin. The nice guy said the part would cost $240.00 + tax+ $36.00 shipping. I've no doubt he's looking up the correct part. He mentioned this was an OEM ICP.
While I would really like to establish a "relationship" with a local dealer, I doubt very much that it will be with this crew.
In my experience, the way I learn an engine is to work on it myself. I've bookmarked a couple legitimate looking IH dealer websites that I'll call and see what they can do for a price. Their shipping is $12.95.
Sounds like I need to find out if I have an early year 1999 or a later year 1999.
Thanks Cadillackid and E450 and Rube for the info and help with the learning curve.
